摘要
数字经济时代,交通运输业与数字技术结合,推动供应链转型升级,对经济高质量发展具有重要意义。本文以2010-2023年沪深两市交通运输业企业为研究样本,检验供应链视角下交通运输业数字化与全要素生产率的关系,并基于调节效应和门限效应模型进行实证分析。结果表明:交通运输业数字化发展能够显著提升企业全要素生产率,且供应链集中度在其中存在正向调节作用并存在单门限效应;资本投入规模在交通运输业数字化发展对企业全要素生产率的影响中存在双门限效应。基于此,应稳步推进数字化战略、加强供应链结构管理和提高自主研发水平,以此推进交通运输业及其供应链数智化、前沿化发展。
In the era of digital economy,the combination of the transportation industry and digital technology to promote the transformation and upgrading of the supply chain is of great significance to the high-quality development of the economy.This paper takes transportation industry enterprises in Shanghai and Shenzhen as research samples from 2010 to 2023 to test the relationship between digitization and total factor productivity in the transportation industry under the supply chain perspective,and conducts empirical analysis based on the moderating effect and threshold effect models.The results show that the digital development of the transportation industry can significantly increase the total factor productivity of enterprises,and there is a positive moderating effect of supply chain concentration with a single threshold effect,and there is a double threshold effect of the size of capital investment in the impact of the digital development of the transportation industry on the total factor productivity of enterprises.Based on this,the digitalization strategy should be steadily promoted,supply chain structure management should be strengthened and the level of independent research and development should be improved,so as to promote the digitalization and cutting-edge development of the transport industry and its supply chain.
